Hw-133-v1.0 Datasheet Direct

Due to its 3A current capability and wide voltage range, the HW-133 v1.0 is frequently found in:

The core performance of the HW-133-V1.0 module is dictated by the underlying MP1584EN IC datasheet. It utilizes synchronous rectification to maintain high conversion efficiency even under heavy loads. Specification Notes / Conditions 4.5V to 28V DC Input must be higher than output Output Voltage Range 0.8V to 20V DC Adjustable via onboard potentiometer Maximum Output Current 3.0 Amperes Peak current rating Continuous Operating Current 1.5 Amperes Recommended without external cooling Maximum Conversion Efficiency Varies based on VINcap V sub cap I cap N end-sub VOUTcap V sub cap O cap U cap T end-sub differential Switching Frequency 1.0 MHz (Typical) to 1.5 MHz (Max) High-frequency reduces ripple Output Ripple Measured at no-load state Quiescent Current Standby mode power draw Operating Temperature -40°C to +85°C Industrial grade operational range Physical Dimensions 22 mm × 17 mm × 4 mm Ultra-small PCB layout footprint Pinout Configuration

Unregulated DC voltage enters via the terminal. A high-frequency, low-ESR ceramic filter capacitor (typically

Operating at a high switching frequency of up to 1.5 MHz allows the board to use physically smaller ceramic capacitors and a tiny inductor while maintaining a clean output ripple of under 30mV. This makes it far smaller than legacy LM2596 step-down modules which operate at a much lower frequency (150 kHz) and require bulky electrolytic capacitors.
